A liquid crystal display device having first and second substrates that face each other, a liquid crystal layer interposed between the first and second substrates, a thin film transistor formed on the first substrate, and a pixel electrode electrically connected with the TFT and including a reflective portion having a reflective electrode and a transmissive portion having a transmissive electrode. The image manager creates an image understanding graph for each of the source images, and also creates a scene representation graph for each of the source images based upon the corresponding subscenes and certain image characteristics. The message is unpackaged by separating the binary attachments from the root document, and the pipeline properties are checked to determine if conversion of the message is required.
